I'm using 1.10.0 and had it working fine, just installed a week or two ago. However now I'm getting the error message of "You have not specified a valid user name" when trying to login with any account. I've checked the mysql database and the usernames are all still in there. The same error occurs when I'm trying to create new users. My LocalSettings.php is available here: http://rafb.net/p/3surPQ55.html
Any help would be appreciated.
Thanks.
Josh
